Abstract (en)
[origin: EP3006751A1] A system (10) for isolating electrical current in an aircraft structure includes a first structure (30) a bearing having an outer race (22) and an inner race (24) and a liner (28) disposed therebetween, the inner race having a second structure (40) coupled thereto. A dielectric seal (26) is secured to the outer race (22) and engages the inner race (24). A conditionally non-conductive gas (60) occupies a sealed chamber (50) that defines a gap (G) between the inner race (24) and the outer race (22). The gap (G) has a predetermined magnitude sufficient to prevent electrical arcing or current leakage between the inner race (24) and the outer race (22) at a first voltage less than that voltage resulting from a lightning strike; and/or to conduct an electrical current between the inner race (24) and the outer race (22) at a second voltage greater than or equal to the voltage resulting from the lightning strike.
